SPECIFICATION forming part of Letters Patent No. 682,401, datedSeptember 10, 1901. Application filed February 12, 1901. erial No.46,959. (No model.)

T0 at whom it may concern:

Beit known that LGEoReE W. BOLTON, Jr. acitizen of the United States,residing at Detroit, in the county of TVayne and State of Michigan, haveinvented certain new and useful Improvements in Repair-Tools, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

The invention has reference generally to a puncture-repair tool forclosing incisions or punctures in elastic tubing-such as bicycletires,hose, &c.--and relates particularly to that type of tool wherein theplugging or filling of the puncture is effected by the insertion throughthe tire-opening of one or more strips or bands, preferably of elasticmaterial.

The invention consists in the novel construction of a repair-tool of thecharacter set forth and in the peculiar arrangement and combination ofits various parts, whereby the bands or strips carried by the tool maybe entirely and quickly disengaged from the latter prior to thewithdrawal of the tool from the tube or even before the initial movementof withdrawal is effected. v In the drawings illustrating my invention,Figure 1 is a vertical central section through the repair-tool. Fig. 2is an elevation of the tool in readiness for use, showing the sameinserted through a puncture-opening in a bicycle-tire. tion through thetool, illustrating the latter as in readiness to be withdrawn from thetubing. Fig. 4 is a sectional view of a portion of the tire, showing thefinished plug therein; and Fig. 5 illustrates a modified construction oftool.

The reference-letter A designates the tool, which, as shown, has oneend, which will hereinafter be termedthe inner end,shaped for insertionthrough the puncture-opening in the tire. The inner end described ispro- 'vided with band-retaining means, which holds the strips or bands,and is further provided with releasing means, hereinafter described,whereby the bands or strips may be immediately and entirely disengagedfrom the inher tool end to permit of the ready withdrawal of the toolfrom the tube.

One form ofconstruction for the tool is as shown in Fig. 1-, wherein thetool is composed Fig. 3 is a vertical central sec-' of two complementarymembers having asliding engagement one with the other. One of themembers is preferably tubular in form, (designated by thereference-letter T3,) the inner end of which is shaped as illustrated topermit of its insertion through the puncture-opening in the tire to berepaired, while at the opposite end it is slightly enlarged, as at O,and carries thereon band-retaining devices, preferably in the form ofpins D. The inner tool member is in the form of a stem E, which slideswithin the outer member and projects beyond the inner end of the latter,forming, in connection with the tubular In ember, a shoulder F, whichconstitutes the bandretaining means at the inmer end of the tool. At itsopposite end the stem is provided with a head G, by means of which thestem may be partially or entirely withdrawn from the outer member topermit of the disengagement of the bands from the tool being eifected.

In operation a plurality of strips, preferably rubber bands, are securedat their inner ends against the shoulder F in the manner shown in Fig. 2and at their opposite ends to the pins D, the stem being extendedthrough the tubular member to form the retainingshoulder. The toolcarryingthe bands thereon is preferably dipped in a liquid cement andthen inserted through the puncture-opening in the tire or tube that isto be repaired, as indicated in Fig. 2. Upon the partial withdrawal ofthe stem the ends of the bands or strips within the tube are immediatelyand entirely disengaged from the inner tool end and subsequently theouter ends of the bands are detached from the pins. The tool being thusentirely freed from the bands at both ends can be readily withdrawn fromthe puncture without any liability of the bands sticking to the tool andbeing withdrawn by the latter from the opening. Upon the withdrawal ofthe tool the bands are allowed to expand, thus entirely filling theopening, and the ends of the bands projecting beyond the exterior of thethe may be clipped off, as indicated in Fig. 4.

In Fig. 5 I have shown the retaining means for the outer band ends ofsuch construction that the bands may be automatically released. Themeans employed consist of fingers or pins a, pivoted between brackets 1)upon an enconsisting of a thread 6, formed upon an en largement at theouter end of the stem, and an internal thread fupon the interior of theenlargement O of the tubular member, with i which the thread 6 engages.In the modification the bands are attached to the tool in the mannerbefore described; but the outer band ends are released first andautomatically upon unscrewing the stem from the outer member.

While I have shown and described different types of the tool, I do notdesire to be limited to the constructions set forth, as it is obviousfrom the modification that various changes could be effected Without inany manner departing from the spirit of my invention, which consists,essentially, of a tool shaped to be inserted within thepunctureopeningin the tube, of band-retaining means upon the inner toolend, and mechanism for entirely disengaging the bands from said tool endwhile the latter is within the tube.

What I claim as my invention is 1. A puncture-repair tool having itsinner end shaped for insertion through a punctureopening in the tube,means at said inner end for retaining strips or bands of material, anddisengaging means at the inner tool end for freeing the latter from thebands or strips after the insertion of the tool within the tube andprior to its withdrawal therefrom.

2. A puncture-repair tool comprising two complementary members shapedfor insertion through the puncture-opening'in the tube,

said members having sliding engagement one With the other and one ofsaid members at its inner end projecting normally beyondthecorresponding end of its complementary member, forming in connectionwith the latter a strip or band retaining shoulder and stripretainingmeans upon one of the members arranged at a distance from said shoulder.

3. A puncture-repair tool comprising an outer member shaped forinsertion through a puncture-opening in the tube and having anenlargement formed upon its opposite end, a plurality of pins pivotallyconnected to the enlargement and adapted to extend at substantiallyright angles therefrom, bearings formed upon the pivot ends of the pins,a stem arranged within the tubular member and projecting normally beyondthe inner end of the latter, said stem having a thread formed upon itsouter end adapted to engage a thread upon the interior of theenlargement, and a head upon the outer stem end constructed to engagethe bearings upon the pins and maintain the latter in their extendedpositions.

4. A puncture-repair tool having its inner end shaped for insertionthrough the puncture-opening, means at said inner tool end for retaininga strip or strips of elastic material, similar means upon said tool at adistance from the inner end thereof, a strip-releasing mechanism fordisengaging the strips from the inner tool end after the insertion ofthe latter within the tube, and means for automatically disengaging thestrips from the band-retaining means at the opposite end of said tool.

In testimony whereof I affix my signature in presence of two Witnesses.
